Hugging Face
Serverless Inference API — 150K+ open models including Llama, Qwen, and FLUX
Hugging Face is the central hub for open-source AI models, hosting 150K+ models across text, image, audio, and video. Its Serverless Inference API provides pay-per-request access to popular open-weight models including Llama 3.3 70B, Qwen 2.5 72B, and FLUX.1-dev — without managing infrastructure. Ideal for developers who want open-weights models without self-hosting.
Stability AI
Stable Diffusion 3.5 Large and Stable Image Ultra — open-weight image generation
Stability AI is the creator of Stable Diffusion, the most widely deployed open-weight image generation model family. The 2026 API offers Stable Diffusion 3.5 Large (highest quality), SD 3.5 Medium (balanced), and Stable Image Ultra for photorealistic output. All SD 3.5 models are open-weight and available for self-hosting. Stability AI also offers Stable Video Diffusion for short video generation.

Key differentiators
The world's largest open-model hub — Serverless Inference API gives instant pay-per-request access to Llama, Qwen, FLUX, and 150K+ other open-weight models without any infrastructure setup.
Stable Diffusion 3.5 models are open-weight and self-hostable — enabling the largest fine-tuning and LoRA ecosystem of any image generation model family, with full control over the generation pipeline.
Frequently asked questions
Hugging Face FAQs
What is the Hugging Face Inference API?
The Hugging Face Serverless Inference API provides pay-per-request access to popular open-weight models including Llama 3.3 70B, Qwen 2.5 72B, and FLUX.1-dev. No infrastructure management required — just an API key.
How much does the Hugging Face API cost?
Serverless Inference API pricing varies by model. Llama 3.3 70B and Qwen 2.5 72B are $0.59/$0.79 per 1M input/output tokens. FLUX.1-dev is $0.025 per image. A free tier is available for low-volume use. See huggingface.co/pricing for current rates.
Can I use my own fine-tuned model on Hugging Face?
Yes. You can deploy your own fine-tuned model on Hugging Face Inference Endpoints (dedicated) or upload it to the Hub for Serverless Inference if it meets the supported architecture requirements.
Stability AI FAQs
What is Stable Diffusion 3.5?
Stable Diffusion 3.5 is Stability AI's latest generation of open-weight text-to-image models. SD 3.5 Large offers the highest quality; SD 3.5 Medium is a balanced option for production use. Both are available for self-hosting.
How does Stability AI compare to FLUX?
FLUX 1.1 Pro generally outperforms SD 3.5 on photorealism and prompt adherence benchmarks. However, SD 3.5 has a much larger community ecosystem of fine-tuned variants and LoRAs, making it more flexible for specialised use cases.
Can I self-host Stable Diffusion 3.5?
Yes. SD 3.5 Large and Medium weights are publicly available under the Stability AI Community License. You can run them on any GPU with sufficient VRAM — SD 3.5 Medium requires ~8GB VRAM; SD 3.5 Large requires ~24GB.
